We demonstrate the design, fabrication and measurement of integrated Bragg gratings in a
compact single-mode silicon-on-insulator ridge waveguide. The gratings are realized by …

Integrated microwave photonics is an emerging field in which photonic integrated
technologies are employed to realize on-chip integration of microwave photonic systems …

We demonstrate, in both theory and experiment, 4-port, electrically tunable photonic filters
using silicon contra-directional couplers (contra-DCs) with uniform and phase-shifted …

A successful design, fabrication and test of silicon photonic circuits requires design tools,
process design kits (PDKs), foundries for fabrication, and test facilities. This paper describes …

A Bragg grating (BG) is a one-dimensional optical device that may reflect a specific
wavelength of light while transmitting all others. It is created by the periodic fluctuation of the …

Properties of reflection and transmission spectral filters based on Bragg gratings in
subwavelength grating (SWG) metamaterial waveguides on silicon-on-insulator platform …

In this paper, we compare the characteristics of several waveguide Bragg gratings (WBGs)
with sinusoidal and rectangular corrugated sidewalls in high confinement integrated optics …

We present a novel silicon photonic biosensor using phase‐shifted Bragg gratings in a slot
waveguide. The optical field is concentrated inside the slot region, leading to efficient light …
